I see quite a few people who have jetting issues with the 01'-03' CR250's. I must be lucky because my 03' CR250 runs awesome with the stock jetting. It accelerates clean from bottom to top with no pinging or burbling. I ride in Fl which is at sea level and the temp is in the high 80's low 90's. With that being said, should I still experiment with different jetting to get more power or leave it alone?
